How this is calculated
Estimates use 2026 tax rules and run entirely in your browser — nothing you type is sent to a server. We compute federal income tax, Social Security, Medicare, and your state's income tax from your gross pay and pre-tax deductions.
Data sources & what's included
- Federal income tax & standard deduction: IRS Revenue Procedure 2025-32 (2026 tax-year rate schedules, all filing statuses).
- Social Security & Medicare: SSA 2026 wage base ($184,500) and IRS Topic 751, including the 0.9% Additional Medicare Tax.
- State income tax: 2026brackets and standard deductions for all 50 states and DC, from the Tax Foundation's 2026 dataset cross-checked against state Departments of Revenue.
Pre-tax deductions: 401(k) reduces income-tax wages but not Social Security/Medicare wages; HSA, FSA, and health premiums reduce both.
Not included: local/city/county income taxes, personal-exemption credits, itemized deductions, tax credits, and deduction phase-outs. Your actual withholding and tax return may differ.
